SOLUTION: There are more than 1/4 million species of beetle. Assume the average length of a beetle is 1cm and the average walking speed is 10 cm per second. These beetles walk up a gang-plan

Question 1052264: There are more than 1/4 million species of beetle. Assume the average length of a beetle is 1cm and the average walking speed is 10 cm per second. These beetles walk up a gang-plank that is 5 meters long onto an ark. They do this in pairs, side by side, one male and one female from each species. The pairs of beetles are spaced so there is a gap of 3 cm between species. How many hours will it take for 1/4 million species of beetles to embark onto the ark once the first pair starts up the gangplank? Hint: PLP

Find time in seconds to cover cm
sec
Now find number of cm intervals in cm
sec
sec for a pair to get into the arc
--------------------------
[ number of species ] / [ species/sec ] = [ sec ]
sec
[ sec ] x [ hrs/secs ] = [ hrs ]
3,472 hrs
--------------
Hope I got it!
